Eastron — equipment and components

Panel power analyzers Eastron

Select Eastron Smart X panel analyzers for instrument replacement and switchboard projects. Specify the panel cutout, current input, measurement functions and communication protocol.

Panel power analyzers

Start with mounting dimensions and the measurement circuit. Then specify whether harmonic readings, digital signals and Ethernet are needed. Functions differ between Smart X variants, so procurement documents should carry the complete model suffix.

Smart X96-5S

A multifunction panel analyzer with 1 A / 5 A inputs, Modbus RTU and harmonic analysis through the 63rd order. Replacement selection should compare the wiring system and measurement accuracy as well as the panel size.

Smart X96-3RC

A 96 × 96 panel analyzer with Rogowski-coil input, pulse output and Modbus RTU. Specify matching sensors as part of the measurement chain and identify any existing integrator separately.

Smart X835

A 96 × 96 instrument with 5 A CT input, pulse output, Modbus RTU and harmonic analysis through the 63rd order. Provide the CT ratio, measurement wiring and the data points required by the monitoring system.

Smart X72-5F / X72-5G

Compact 72 × 72 panel instruments with 5 A input and Modbus RTU. X72-5G adds digital inputs and outputs. For a replacement, document the occupied terminals and the connected signal specifications.

Smart X96-1A

A version with RJ-connected CTs and 100 mA input. The catalog specifies pulse output, Modbus RTU and harmonics through the 63rd order. Identify the connector arrangement and the exact sensors in the proposed set.

Smart X96-5J

A 96 × 96 panel analyzer with 5 A input, digital signals and Ethernet. It supports Modbus RTU / TCP and a gateway function. Include the network layout between the switchboard and the supervisory system.

Choose the equipment group

For consumption metering, start with SDM or DCM and define AC or DC operation and the connection method. Consider Smart X when the project requires network parameters and harmonic readings. If the instrument stays in place but an external sensor needs replacing, use the current-transformer group.

An ESP gateway transports data already measured by another device. The monitoring group covers projects with multiple measurement points. Time-delay and weekly-schedule tasks belong to ESRD and ESRS. This separates the required device from its function in the wider installation.

Specify an installed-device replacement

Photograph the front and side identification, terminal markings and the installation space. Transcribe the full model suffix. If the circuit includes CTs or a shunt, identify those components separately; the meter name alone does not define the complete measurement set.

State whether you need one instrument, a set with sensors or equipment for several identical panels. Describe an observed failure such as a blank display, missing communication or inconsistent readings. This helps distinguish a replacement purchase from a measurement-chain investigation.

Current input, protocol and scope of supply

Separate the primary current from the signal reaching the instrument. Inputs rated at 1 A / 5 A, 40 mA, 100 mA, 100 mV and Rogowski-coil inputs require the corresponding sensors. The power-circuit current rating alone does not specify the instrument variant.

For RS485, provide the protocol, addresses, speed and communication format. For Ethernet, define the device role and receiving system. List the meters, sensors, connecting cables, converters and mounting items actually required as separate entries in the scope of supply.

Inverter and charging-station projects

For an inverter, identify the exact model, software version and meter location in the power diagram. Include the supported-device list from the inverter documentation where available. Compatibility assessment concerns the specific device pair, including registers and energy-flow direction.

For a charging station, state AC or DC operation, the working range and power connection. Add any need for a separate display or multiple communication ports. Compare market-specific variants using the complete ordering code and project documentation.

Prepare a sourcing request

Send the ordering code or photographs, required quantity and delivery destination. If identification is incomplete, include the relevant wiring-diagram section and explain the device function. For a new installation, provide a specification with a separate line for each instrument type.

The quotation should be compared with the requested variant and set contents. State whether an alternative may be proposed for engineering review. For multiple panels, distinguish the quantity per panel from the total procurement quantity.

Quotation and project confirmation

Availability, price, lead time, compatibility and included components are confirmed for the selected variant after reviewing the request. No authorized-dealer status is claimed. MID, UL/ETL or PTB/Eichrecht identification must be checked against the exact instrument and project requirements.
